Vintage Guild Picture Puzzle Whitman Marina Grande Capri 304 Pcs Complete

Lovely vintage puzzle ‘Marina Grande Capri’ by Whitman Publishing Co. The puzzle shows Polly Jackson’s signature but I don’t see her credited on the box. It’s a bit challenging because not all pieces interlock. They are cut in such a way they the nest next to one another. In great condition with minor wear. Please see photos. The box has wear on the corners but is fully intact.
